Definitions
- the present invention provides a formulation for improving solubilization and bioavailability of hydrophobic and lipophilic compounds.
- Encapsulation is an expanding technology, with great potential in several areas, including the pharmaceutical and food industries.
- the delivery of bioactive compounds into the human body is highly affected by particle size, thus nanoencapsulation is an option to enhance bioavailability of such compounds.
- Nanoencapsulation of bioactive components, with poor solubility in aqueous solutions, can improve their dispersibility in water, and therefore also their bioavailability and bioactivity.
- Protein-based nano-encapsulation technologies have been found effective in protecting the encapsulated bioactive during thermal treatment, exposure to UV or visible light, low pH, and during shelf life and digestion. Undesired sensory attributes like bitterness and astringency were masked, and the high bioavailability of nano- encapsulated nutraceuticals was clinically demonstrated in humans. Bioavailability of vitamin D was found to be comparably high in protein nanoparticles as in milk fat in a clinical study. However, there is still lack of natural, plant passed, non-allergenic encapsulation materials and techniques, which may not only improve dispersibility, and protect the bioactives, but also improve their bioavailability.
- Astaxanthin (3,3’-dihydroxy-P-P-carotene-4,4’-dione) is a xanthophyll carotenoid found mainly in algae and marine animals, notably salmon, conferring their characteristic red-orange color. It can be synthesized only by few microorganisms, especially the green microalga Haematococcus Pluvialis.
- PP has been shown to be greater than that of other vegetable and cereal proteins, higher than casein and comparable to the nutritional value of whole egg.
- PP is produced from widely available and inexpensive raw materials and is a by-product of potato starch production.
- PP is considerably amphiphilic and water-soluble, so that it can be particularly useful for the encapsulation and solubilization of hydrophobic compounds with low water- solubility.
- PP comprises several fractions, mainly patatin, protease inhibitors, and higher molecular weight proteins.
- the patatin or patatin-rich fraction is well digestible.
- Lecithin is a mixture of several phospholipids containing mainly phosphatidylcholine, phosphatidylethanolamine and phosphatidylinositol.
- LEC is widely used as an emulsifier, viscosity regulator, anti- spattering and dispersing agent.
- LEC is absorbed in the human body as a lipid, assisted by bile salts. The presence of fat, fatty acids and lipids in the formulation increases the excretion of bile salts, thus it may enhance the bioavailability of AX and other lipophilic compounds.
- AX is a strong antioxidant due to its many conjugated double bonds. It exhibits antioxidant activity stronger than the activities of vitamin E and b-carotene, which is attributed to its strong reactive-oxygen-species quenching activity.
- Curcumin is a natural polyphenol compound, found in the turmeric plant. Curcumin aids in the management of oxidative and inflammatory conditions, metabolic syndrome, arthritis, anxiety, and hyperlipidemia. Most of these benefits can be attributed to its antioxidant and anti-inflammatory effects.
- a major limitation of AX and curcumin is a low bioaccessibility and bioavailability, which stems from the fact that both compounds are almost insoluble in an aqueous solution.
- bioavailability of a hydrophobic compound, such as AX may be enhanced by using a bioavailability enhancer, such as quercetin (QUE).
- a bioavailability enhancer such as quercetin (QUE)
- QUE quercetin
- QUE was found to inhibit cytochrome P-450 activity, and also P-glycoprotein, the efflux transporter which inhibits the absorption of numerous hydrophobic compounds. Additionally, bioavailability enhancers such as curcumin and rutin were found to inhibit P-glycoprotein and cytochrome P-450. Hence, without being limited to any particular mechanism or theory, it was hypothesized that encapsulation of bioavailability enhancers, such as QUE within a core-shell particle may enhance bioavailability and/or bioaccessibility of a hydrophobic compound, by reducing both efflux of the hydrophobic compound back into the intestinal lumen by P-gp, and its elimination by intestinal and/or hepatic cytochrome P-450.

Description
FORMULATIONS FOR ENCAPSULATION AND BIOAVAILABILITY IMPROVEMENT OF BIOACTIVE COMPOUNDS BASED ON NATURAL
PLANT BASED MATERIALS
CROSS REFERENCE TO RELATED APPLICATIONS
[01] This application claims the benefit of priority of U.S. Provisional Patent Application No. 62/832,377 filed April 11, 2019 entitled "FORMULATION FOR SOLUBILIZATION OF BIO ACTIVE COMPOUNDS", the contents of which is incorporated herein by reference in their entirety.
FIELD OF INVENTION
[02] The present invention provides a formulation for improving solubilization and bioavailability of hydrophobic and lipophilic compounds.
BACKGROUND OF THE INVENTION
[03] Numerous bioactive compounds, including nutraceuticals and drugs, are poorly bioavailable, due to their poor solubility, and often also due to the action of either efflux transporters, like P-gp, or of detoxification enzymes, like Cytochrome P 450 enzyme family, or both.
[04] Encapsulation is an expanding technology, with great potential in several areas, including the pharmaceutical and food industries. The delivery of bioactive compounds into the human body is highly affected by particle size, thus nanoencapsulation is an option to enhance bioavailability of such compounds. Nanoencapsulation of bioactive components, with poor solubility in aqueous solutions, can improve their dispersibility in water, and therefore also their bioavailability and bioactivity.
[05] Protein-based nano-encapsulation technologies have been found effective in protecting the encapsulated bioactive during thermal treatment, exposure to UV or visible light, low pH, and during shelf life and digestion. Undesired sensory attributes like bitterness and astringency were masked, and the high bioavailability of nano- encapsulated nutraceuticals was clinically demonstrated in humans. Bioavailability of vitamin D was found to be comparably high in protein nanoparticles as in milk fat in a clinical study. However, there is still lack of natural, plant passed, non-allergenic
encapsulation materials and techniques, which may not only improve dispersibility, and protect the bioactives, but also improve their bioavailability.
[06] Astaxanthin (AX) (3,3’-dihydroxy-P-P-carotene-4,4’-dione) is a xanthophyll carotenoid found mainly in algae and marine animals, notably salmon, conferring their characteristic red-orange color. It can be synthesized only by few microorganisms, especially the green microalga Haematococcus Pluvialis.
[07] To improve the bioavailability of AX several approaches were evaluated in order to find appropriate biomaterials, which would solubilize or disperse hydrophobic compounds such as AX in water, and facilitate its intestinal absorption.
[08] The nutritional value of PP has been shown to be greater than that of other vegetable and cereal proteins, higher than casein and comparable to the nutritional value of whole egg. PP is produced from widely available and inexpensive raw materials and is a by-product of potato starch production. Furthermore, PP is considerably amphiphilic and water-soluble, so that it can be particularly useful for the encapsulation and solubilization of hydrophobic compounds with low water- solubility. PP comprises several fractions, mainly patatin, protease inhibitors, and higher molecular weight proteins. In particular, the patatin or patatin-rich fraction is well digestible.
[09] Lecithin (LEC) is a mixture of several phospholipids containing mainly phosphatidylcholine, phosphatidylethanolamine and phosphatidylinositol. In the food industry, LEC is widely used as an emulsifier, viscosity regulator, anti- spattering and dispersing agent. LEC is absorbed in the human body as a lipid, assisted by bile salts. The presence of fat, fatty acids and lipids in the formulation increases the excretion of bile salts, thus it may enhance the bioavailability of AX and other lipophilic compounds.
[010] AX is a strong antioxidant due to its many conjugated double bonds. It exhibits antioxidant activity stronger than the activities of vitamin E and b-carotene, which is attributed to its strong reactive-oxygen-species quenching activity. Curcumin is a natural polyphenol compound, found in the turmeric plant. Curcumin aids in the management of oxidative and inflammatory conditions, metabolic syndrome, arthritis, anxiety, and hyperlipidemia. Most of these benefits can be attributed to its antioxidant and anti-inflammatory effects. A major limitation of AX and curcumin is a low bioaccessibility and bioavailability, which stems from the fact that both compounds are almost insoluble in an aqueous solution.
[011] In some embodiments, dissolving AX in olive oil, followed by its emulsification with PPs, or dissolving AX in ethanol with lecithin, and then mixing with PP solution, was hypothesized to provide additional improvement of the bioavailability while still maintaining the consumer-friendly “All- Natural Ingredients” labeling. In some embodiments, bioavailability of a hydrophobic compound, such as AX may be enhanced by using a bioavailability enhancer, such as quercetin (QUE). Without being limited to any particular mechanism or theory, it is postulated that a hydrophobic compound, such as AX is metabolized primarily by hepatic cytochrome P-450 1A1/2. QUE was found to inhibit cytochrome P-450 activity, and also P-glycoprotein, the efflux transporter which inhibits the absorption of numerous hydrophobic compounds. Additionally, bioavailability enhancers such as curcumin and rutin were found to inhibit P-glycoprotein and cytochrome P-450. Hence, without being limited to any particular mechanism or theory, it was hypothesized that encapsulation of bioavailability enhancers, such as QUE within a core-shell particle may enhance bioavailability and/or bioaccessibility of a hydrophobic compound, by reducing both efflux of the hydrophobic compound back into the intestinal lumen by P-gp, and its elimination by intestinal and/or hepatic cytochrome P-450.

Materials and Methods
System characterization
[0284] Particle size distribution of Astaxanthin-Potato Protein (AX-PP), Astaxanthin- Lecithin-Potato Protein (AX-LEC-PP), pure curcumin, CUR-PP and CUR-LEC-PP samples was determined using a NICOMP DLS analyzer. Particle size distribution of Astaxanthin-Olive oil-Potato Protein (AX-Olive oil-PP) emulsion and of CUR-Olive oil-PP emulsion was determined using a Malvern Mastersizer 3000. Statistical analysis of the results was performed using Microsoft EXCEL 2013. The samples were tested in duplicate.
[0285] Crystal formation and particles stability were studied by light microscopy, as ways to determine optimal loading capacity, using an Olympus DP71 digital camera connected to an Olympus BX51 light microscope, operated in a bright-field optical mode or in polarized light optics.
Freeze drying and reconstitution
[0286] Samples were freeze dried using Labconco benchtop Freeze Dryer overnight and kept at -20°C until analysis. Before simulated digestion or particle size analysis, the samples were reconstituted to the initial volume with distilled water and kept at - 20°C until simulated digestion or particle size analysis.
Simulated digestion
[0287] Simulated gastric and intestinal digestion was based on the protocol described by Minekus et al. Food Funct., 2014, 5, 1113-1124. To evaluate CUR protection, the digested samples underwent extraction and the CUR content was determined by
spectrophotometer with l=420hih. To evaluate CUR bioaccessibility, the digested samples underwent ultra-centrifugation (15,000 rpm, 30 min., 20°C), the upper liquid was collected and its CUR content was determined by extraction and spectrophotometry (absorbance at l=420hhi). Extraction by phase separation was achieved by adding ethyl acetate and ethanol (2:1 v/v), followed by lmin of vortex. 500m1 of water were then added to each test tube and vortexed for 20sec. The samples were then centrifuged for 5 min at 5,000 G at 25 °C. The upper layer of ethyl acetate containing CUR was removed and the steps of addition of 1 ml of ethyl acetate were repeated once more. The ethyl acetate was evaporated from the extract under a flow of nitrogen, and reconstituted in a known volume of ethanol.
EXAMPLE 1
Encapsulation of Astaxanthin by Astaxanthin-Potato Protein nanoparticles formation
[0288] An ethanolic stock solution of Astaxanthin (AX) oleoresin was added dropwise into potato protein (PP) solution (in phosphate buffer, pH=7) to obtain two different molar ratios (AX in excess). The molar ratios obtained were 1: 1 and 2: 1 (AX:PP). The concentration of AX was 0.5 mM in all samples.
EXAMPLE 2
Encapsulation of Astaxanthin by Astaxanthin-Lecithin-Potato Protein
nanoparticles formation
[0289] A pre-mix of the AX stock solution with the ethanol- soluble fraction of sunflower lecithin (LEC) in ethanol was prepared (equal concentration of AX and LEC, 5 mM). The pre-mix was added dropwise into PP solution (in phosphate buffer, pH=7) to obtain different molar ratios (AX and LEC in excess). The molar ratios obtained were 1: 1: 1 and 2:2: 1 (AX:LEC:PP). The concentration of AX was 0.5 mM in all samples.
EXAMPLE 3
Encapsulation of Astaxanthin in Astaxanthin-Olive oil-Potato Protein emulsion
[0290] A pre-mix of AX oleoresin and refined olive oil (1:3 w/w AX Oleoresi Olive oil) was left shaking in 50°C for 30 min until the mixture was homogenous. PP solution (in phosphate buffer, pH=7) was added to the AX:01ive oil mixture. Two different proportion were tested - 1:3:4 w/w AX OleoresimOlive oikPP in the final solution
(4%oil) or 0.5: 1.5:4 w/w AX Oleoresi Olive oil:PP in the final solution (2%oil). Then, the mixture was pre-homogenized using a desktop homogenizer (30,000 rpm, 5 min). The pre-emulsion was homogenized using a high-pressure homogenizer (Emulsiflex C3, Avesin, 950 bar, 4 passes).
EXAMPLE 4
Encapsulation of Curcumin in Curcumin-PP-Olive oil emulsion
[0291] Curcumin was dissolved in ethanol. The ethanolic curcumin solution was then added into a PP solution while stirring. Olive oil was then added while prehomogenizing, using a desktop homogenizer (30,000 rpm, 5 min). The pre-emulsion was homogenized using a high-pressure homogenizer (Emulsiflex C3, Avesin, 950 bar, 4 passes).
EXAMPLE 5
Simulated digestion of the powders and evaluation of Astaxanthin in-vitro bioaccessibility
[0292] Simulated gastric and intestinal digestion was based on the protocol described by Minekus et al. Food Funct., 2014, 5, 1113-1124. To evaluate AX bioaccessibility, the digested samples underwent ultra-centrifugation (15,000 rpm, 30 min., 20°C), the upper liquid was collected, and its AX content was determined by extraction and RP- HPLC (reversed-phase HPLC). Extraction by phase separation was achieved by adding dichloromethane and methanol (1:3 v/v), followed by 20 s of vortexing. 2 ml of dichloromethane were then added to each test tube and vortexed for 1 min. The samples were then centrifuged for 10 min at 1,500 G at 4°C. The bottom layer of dichloromethane containing AX was removed and the steps of addition of 2 ml of dichloromethane were repeated twice more. The dichloromethane was evaporated from the extract under a flow of nitrogen. Subsequently, the extract was reconstituted in a known volume of ethanol. Exemplary results of these experiments are represented in Figure 8.
EXAMPLE 6
Scaled-up production of Astaxanthin-Olive oil-Potato Protein emulsion
[0293] After the identification of the most bio-accessible formulation, changes were made in order to produce the capsules for the clinical trial. AX-Olive oil-PP emulsion
was made as described above with slight changes. First, the 4% oil formulation was made using semi-industrial equipment (Nano DeBEE, 1900 bar, 2 passes). In order to increase AX percent in the final powder, the proportions in the formulation were changed to 1:2:3 w/w Oleoresi Olive oihPP in the final solution and Tapioca Maltodextrin was added (1/20 w/w of the protein amount). Particle size distribution and bioaccessibility was evaluated as described above.
EXAMPLE 7
Clinical trial for examining in-vivo bioavailability of AX
[0294] The in-vivo bioavailability of the most bio-accessible formulation was evaluated and compared to AX oleoresin. The study explored the bioavailability of AX in humans by comparing 2 different formulations which include AX: (A) AX oleoresin; (B) the most bio-accessible formulation of Example 5. The 2 formulations were compared in a single dose (15 mg AX) by 13 volunteers per formulation, in a randomized double-blinded cross-over design, in Rambam Health Care Campus. After a night fast, a blood sample was taken from each volunteer (t=0) and a fat-free yogurt was consumed by the volunteers. After 15 min each volunteer consumed 4 AX capsules (formulation A or B) and blood samples were collected after 2, 4, 6, 8, 10, 24, 48 and 72 hr. The AX in the blood samples was analyzed by RP-HPLC after extraction as described above. The results of the study are summarized in Figures 11 and 12. Formulation B significantly increased the bioavailability of AX, as compared to formulation A.
EXAMPLE 8
Encapsulation of CUR-PP, CUR-LEC-PP, CUR-Olive Oil-PP
Stock solutions preparation
[0295] PP was dissolved in phosphate buffer (pH = 7) at 37°C for 45 min, while stirring (PP cone. 1 mM). After cooling to room temperature, the solution was centrifuged to precipitate insoluble matter (3000 rpm, 5 min). The supernatant was collected and filtered by vacuum filtration (0.45 pm filter). The final protein cone was determined by spectrophotometer (277 nm). Pure curcumin (CUR) powder (95%) was dissolved in absolute ethanol at 40°C for 30 min, while stirring, to obtain ethanolic CUR stock solution (7.5 mM). Sunflower LEC was dissolved in 20 ml of absolute ethanol for 2 hr
(LEC cone. 27 mM). The solution was centrifuged for 10 min at 5000 rpm. The supernatant containing the ethanol soluble fraction of LEC was collected. The final cone was determined gravimetrically by evaporating the ethanol from the supernatant and was found to be 12.8 mM.
CUR-PP nanoparticles formation
[0296] An ethanolic stock solution of curcumin powder was added dropwise into PP solution, during vortex, and left shaken for 1 hr. CUR concentration was 1.5 mM in all samples. Examplary results, showing enhanced bioaccessibility of curcumin, are depictedby Figure 16.
CUR-LEC-PP nanoparticles formation
[0297] Pure curcumin (CUR) powder (95%) was dissolved in LEC ethanolic solution at 40°C for 30 min, while stirring (equal concentration of CUR and LEC, 10 mM each). The CUR-LEC ethanolic solution was added dropwise into PP solution, during vortex and left shaken for 1 hr. CUR concentration was 1.5 mM in all samples.
CUR-Qlive oil-PP emulsion preparation
[0298] CUR-PP nanoparticles were formed as mentioned above, in 9: 1 molar ratio (CUR:PP, 0.06%:0.73% w/v in buffer). After 1 hr. shaking, the NPs solution was mixed with olive oil and pre-homogenized using a desktop homogenizer (30,000 rpm, 5 min) (final cone of the oil was 0.73% w/v in the buffer). The pre-emulsion obtained was homogenized using a high-pressure homogenizer (Emulsiflex C3, Avesin, 950 bar, 4 passes).
[0299] The abovementioned particles (CUR-LEC-PP, CUR-Qlive oil-PP) undergo biological studies, so as to evaluate the potential bioaccessibility and/or bioavailability of these molecules versus non-encapsulated curcumin. It is postulated, that such particles will exhibit an increased bioaccessibility and/or bioavailability, as well-known from studies performed on curcumin encapsulated by PP, and as represented by Figure 17 showing an increased protection of the encapsulated curcumin (Curcumin-PP- Lecithin) as evaluated in the simulated digestion model (described hereinabove in Example 5).
Free CUR sample preparation (control)
[0300] An ethanolic stock solution of curcumin powder was added dropwise into phosphate buffer, during vortex, and left shaken for 1 hr. CUR concentration was 1.5 mM in all samples.
